Ok, this is pretty awesome. Alot of it is pretty damn hard, but it's really cool.
It's a promo thing for Dark M&Ms, but very well done. It's a painting, with images representing 50 "Dark" Movies (Horror, Thriller, Film-Noir, ect.) hidden through it.
Ive been playing for like half an hour...I must say, Im kind of stuck.
